    Beef up your BB.

    The 86mm bottom bracket is a relatively new, reasonably beefier BB standard that allows frame designers a little more leeway to play around with seat tube, downtube, and chainstay designs. The new, larger shell requires a larger bracket, obviously, and Shimano designed the Dura-Ace BB86 Bottom Bracket to quite literally fill the gap. While it's a little larger than traditional BBs, the BB86 has the same design as Shimano's other Dura-Ace brackets, with steel cartridge bearings packed inside composite cups and plastic o-rings and dust shields to keep everything running smoothly. The 86 is also compatible with Shimano HollowTech cranks, so you can keep your old crankset even if you're getting a new frame.

    Smooth and maintenance free, isn't that what we want out of a BB? it is for my and after a summer of commuting, training, racing, I don't even have to think about it, it's always dependable.

    Unanswered Question

    I currently have this BB in my bike with an Ultegra 11 speed crankset on a Merckx emx-7. I was thinking of getting a FSA Slk-k light 386evo crankset. Can you tell me if this would work or would I need another BB or some adapters?
